Upon pressing arm or operating member 25 tension will beexerted on wire 5l by reason of the connection above described and thesaid wire will cause the partial rotation of the valve stem 20, therebypermitting air to pass through the inlet 18 into the chamber 16 at apoint directly below, the feed tube 25, thereby forcing the powder orliquid upwardly through thel the bottom of the chamber being depressedbelouT the end of the tube permitting the material to be fed by gravityto a point between the inlet and the lower end of the tube and -adischarge nozzle having connection with the upper end of said tube.

2. In a device of the class described, a receptacle comprising an upperchamber for receiving the material to be sprayed, a lower chamber forcontaining air under pressure,

air compressing means, a partition member separating said chambers andbeing downwardly deected at its central portion, said central portionhaving an air inlet, a valve neem-efr controlling said inlet, a feedtube positioned lower chamber adapted to contain air under pressure, aircompressing means connected with said lower chamber,a partition meinberseparating the chambers, 'said member having a depressed central portionand being provided with an air inlet at said central portion, a valvecontrolling the inlet, a tube extending vertically through the eentralportion of the upper chamber and terminating at a point above the inlet,said inlet being in alinement with the longitudinal axis of the tube, anozzle connected with the upper end of said tube, an operating memberpivoted'on said nozzle, a spring controlling the position of saidmember, a tube extending downwardly from said noz` zle, over the top ofthe receptacle and downwardly along the side wall of said receptacle,and a flexible device operating within said tube and having connectionwith said valve for controlling the position of the latter.

In testimony whereof I affix my signature.
